Due to their personality, both gaara and hachiman is not a type of guy who smiles easily. So, when they finally smile, i find it really sweet. Although the smile is not much, but both of them looks cute too..

Also, I've been having SERIOUS problems with this guy. I'm fairly certain I've seen his character design somewhere before (this guy is Makoto Tachibana from Free!, a swimming anime). The guy I'm looking for has that EXACT SAME smile, and similar-shaped eyes (he has his eyes open in this shot: http://media.tumblr.com/38d71ef307dd79f8e697b696ff380e2d/tumblr_inline_mqk0fu3FGX1r9u0at.jpg). The art style of the anime I'm thinking of is also nearly exactly the same as Free!. *scratches head* The closest match I could find was Teppei Kiyoshi from Kuroko no Basket, but it's NOT him... (Teppei does have an adorkable smile, though.)
